Crawler-type traveling mode：The robot tank adopts a crawler-type traveling mode, which can rotate 360 degrees, with stable operation and strong passability.
Robotic arm function (optional)： 4-degree-of-freedom robotic arm, 180-degree free rotation, unique APP control interface, synchronous control of the virtual robotic arm, and control the grasping movement of the robotic arm as you like.
WIFI wireless remote control： After the car is turned on, it generates a WiFi signal. The mobile phone or tablet can connect to the car through WiFi and control it with a dedicated APP.
Bluetooth wireless remote control： After the car is turned on, it sends out a Bluetooth signal, and the mobile phone uses a dedicated APP to control the car.
Real-time video transmission：Through WiFi, real-time transmission of video images captured by the camera of the car to the APP or computer control software interface to achieve first-person visual effects.
Ultrasonic obstacle avoidance：Triggered by the control terminal, through the distance detection function of the ultrasonic sensor, the car stops when it encounters an obstacle
Ultrasonic distance measurement feedback：Triggered by the control terminal, the distance between the car and the obstacle can be seen on the radar interface of the APP or PC software, and the distance value in cm is clearly displayed.
Infrared patrol function：The car recognizes the black patrol line arranged on the ground through the infrared photoelectric sensor, and automatically follows the patrol line.
Two-degree-of-freedom pan/tilt：You can flexibly control the up, down, left, and right rotation of the pan/tilt by dragging the mobile phone touch screen or the computer mouse, and freely control the camera angle as you like.
Camera visual line inspection：The car recognizes the black patrol line arranged on the ground through the camera, and automatically follows the patrol line.
Road planning function：Draw the path in the mobile APP or PC interface, and the car will drive according to the planned path
